In a frequency distribution, ogives are graphical representation of (a) Frequency                          (b)  Relative frequency (c) Cumulative frequency       (d)   Raw data

Answer

To solve the question regarding what ogives represent in a frequency distribution, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Ogives**:
An ogive is a graphical representation that shows the cumulative frequency of a dataset. It helps in understanding how many data points fall below a certain value.

2. **Identify the Components of an Ogive**:
In constructing an ogive, we plot points using the upper class limits of the data intervals against their corresponding cumulative frequencies.

3. **Define Cumulative Frequency**:
Cumulative frequency is the sum of the frequencies for all classes up to a certain point. It tells us how many observations fall below a particular class limit.

4. **Analyze the Options Given**:
- (a) Frequency: This represents the number of occurrences of each class interval.
- (b) Relative frequency: This is the frequency of a class divided by the total number of observations.
- (c) Cumulative frequency: This is the total frequency accumulated up to the upper class limit.
- (d) Raw data: This is the original data set without any processing.

5. **Determine the Correct Answer**:
Since ogives are based on cumulative frequencies, the correct answer is (c) Cumulative frequency.

### Final Answer:
(c) Cumulative frequency
